Many thanks, of troy. The knitted sock footprint in the mud of the tomb story was the best! Positively Holmesian.

Now back to the question and your comment:

Crochet is rather new, only about 300 to 400 years old, and it was created (some say by french nuns) to make a kind of lace (that would be exempt from sumptuary laws--there is a short thread about sumptuary laws, too, not to old down here somewere)

To repeat the obvious: Lace apparently may be either knitted or crocheted. Correct?
